In the world of effects there are some stompboxes that have become the stuff of myth and legend - some purely for their sound, others for their rarity value.
The Ampeg Scrambler is one of a small set that has become legendary on both counts.
It has a unique and sought after upper octave fuzz sound, but you'd have more chance of finding Elvis stacking shelves in your local Tesco than finding one second-hand market.
It sounds like the perfect excuse for a reissue, then. Which is just what Ampeg has done.

SCR DI

The Scrambler Series Pedals are based on the cosmetic design of the original Ampeg Scrambler pedals from 1969. Our SCP-OCT Bass Octave Pedal features the Octave Divider circuit used on the popular SVT-5PRO, duplicating the input signal one octave lower. This circuit tracks fast and holds the note, even at low volumes. The SCP-OCT is a great addition to your tone arsenal.
